OPERATION
SAFETY
1. Table power must be ON before permitting a patient to either get on or off the table.
The table locks will not operate without power.
2. Extreme care must be taken during the changing of the table height to insure that
both the patient and operator are clear of tubestand equipment and areas around
the Bucky.
TABLE CONTROLS
FOOT PEDAL SYMBOLS AND FUNCTIONS
The DOWN switch pedal commands motorized lowering of the tabletop down to a
minimum of 20.62 inches (52.5 cm) above the floor level.
The table top will move downward at a constant speed as long as the pedal is depressed.
Automatic shutdown of the downward movement takes place at the exposure position and
the lowest limit switch position.
The position of the exposure switch (normally at 40 inches S.I.D.) depends on the physical

configuration of the system. This switch is preset at the factory and will need to be
repositioned at the time of installation.
To continue downward movement beyond the exposure position, release switch pedal and
then depress it again. The tabletop may now be lowered to its minimum height.
The UP switch pedal commands motorized raising of the table top up to a maximum of
33.5 inches (85 cm) above floor level.
The table will move upward at a constant speed as long as the pedal is depressed.
Automatic shutdown of the upward movement takes place at the exposure position and at
the highest limit switch position.
To continue upward movement beyond the exposure position, release the switch pedal
and then depress it again. The tabletop may now be raised to its maximum height.
The tabletop switch pedal unlocks the brakes for the floating tabletop. As long as the pedal
is depressed, the table top can be moved manually in the longitudinal and transverse
directions. Releasing the pedal will lock the table top in its new working position.
Depressing the PUSHBUTTON on the Bucky Pushbutton Carriage releases the
electro-magnetic lock. As long as the PUSHBUTTON is depressed the Bucky can be
moved to the desired position. Releasing the PUSHBUTTON secures the Bucky.

©Del Medical Imaging June 7, 2002 page 9 of 31 pages
The EV 200 Elevating Table is ready for operation as soon as power is applied and the
generator is turned on. Refer to the manufacturer's instructions concerning the start-up of
the generator.
REQUIRED PREVENTATIVE MAINTENANCE
In order to assure continued safe performance of this equipment, a preventive
maintenance program must be established. It is the owner's responsibility to arrange for
this required service.
Maintenance procedures for the EV200 are required within 30 days after completion of
the installation and every 6 months thereafter. Safe equipment performance also
requires the use of service personnel who are specifically trained and experienced with
medical x-ray apparatus. Applicable preventive maintenance or any repair service should
be performed by these skilled individuals.
Maintenance information is divided into two parts. The Service Adjustments and
Periodic Maintenance chapters of this manual cover those inspections, procedures and
recalibrations which must be performed at specified intervals by qualified service
personnel. User Service and Maintenance covers inspections to be made by the user
to confirm continued operation and absence of physical damage.
USER SERVICE AND MAINTENANCE
Cleanliness is a fundamental rule in maintaining equipment. At least once a month,
external metallic surfaces and exposed tracks should be wiped to remove dust build-up
or any other foreign material that may have accumulated. If the tracks are wiped with a
cloth slightly moistened with light oil, sufficient lubrication will be provided to ensure
smooth operation and to protect against rust. Painted metal surfaces should be cleaned
using a clean cloth slightly moistened in clean water. Do not use cleaners or solvents of
any kind as they may dull the finish. Polish with PURE liquid or paste wax. Do not use a
wax containing a cleaning substance.
Note: This x-ray equipment contains operating safeguards to ensure maximum safety.
Aside from routine maintenance, any abnormal noise, vibration or unusual performance
should be investigated by a qualified service technician. Before requesting service,
however, be sure the equipment is being operated according to instructions.

18.Temporarily turn power to the table ON and ensure that the collision sensor
switches and adjustable tension bearing assemblies are working properly. The
adjustable bearing should be riding lightly on the lower surface of the table top
guide rail and the collision sensing switch should allow the table elevator to operate
in the DOWN direction.
19.A second person should lift up on any corner of the table top while the installer or
field service engineer depresses the DOWN foot pedal. If the switch is properly
adjusted, the DOWN command will be inhibited. Each switch should be checked in
this manner, before remounting the table top bumper stops. If the switches fail to
operate properly, refer to the instructions for calibrating the collision sensing
switches in the Test and Calibration chapter of this manual.
ALTERNATE METHOD OF MOUNTING TABLE TOP IN SMALL ROOMS
If the room is too small to allow the table top to be installed in this manner:
•Remove the bumper stops from both ends of the table top, and remove the
adjustable tension bearing assemblies and plastic guide rollers from the front rail
of the inner frame.
•Install the table top by lifting it at the front of the table to about a 45 degree tilt so
that the rear rail fits over the rear bearings and guide roller. Lower the front of
the table top and shift it from one end and then the other to reinstall the front
bearings assemblies and guide roller.
•Reinstall the bumper stops at both ends of the table top. Check table top with
level in both directions and adjust by shimming the base if necessary.
20.Set the 40 inch S.I.D. limit switch so that film plane of the Bucky tray is 40 inches
from the x-ray source when the switch is depressed and the table comes to rest.
The switch may be moved along its mounting bracket by loosening the two
mounting screws.
CAUTION
Be sure the red panic switch is depressed before adjusting the limit switch. Take
care that the limit switch roller projects only far enough to engage the actuator.
Otherwise, the actuator may damage the roller, particularly when the table is
descending.
The switch position should be set when the table stops while elevating. Note that
